| CVE-2024-25629 | — | < 1.19.1-2.el9_4 | 1.19.1-2.el9_4 | Feb 23, 2024 | c-ares is a C library for asynchronous DNS requests. `ares__read_line()` is used to parse local configuration files such as `/etc/resolv.conf`, `/etc/nsswitch.conf`, the `HOSTALIASES` file, and if using a c-ares version prior to 1.27.0, the `/etc/hosts` file. If any of these conf | ||
| CVE-2020-22217 | — | < 1.13.0-9.el8_9.1 | 1.13.0-9.el8_9.1 | Aug 22, 2023 | Buffer overflow vulnerability in c-ares before 1_16_1 thru 1_17_0 via function ares_parse_soa_reply in ares_parse_soa_reply.c. | ||
| CVE-2023-32067 | — | < 1.17.1-5.el9_2.1 | 1.17.1-5.el9_2.1 | May 25, 2023 | c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 lengt | ||
| CVE-2023-31147 | — | < 1.19.1-1.el9 | 1.19.1-1.el9 | May 25, 2023 | c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom() are unavailable, c-ares uses rand() to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand() so will generate predictable output. Input from the ra | ||
| CVE-2023-31130 | — | < 1.19.1-1.el9 | 1.19.1-1.el9 | May 25, 2023 | c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an | ||
| CVE-2023-31124 | — | < 1.19.1-1.el9 | 1.19.1-1.el9 | May 25, 2023 | c-ares is an asynchronous resolver library. When cross-compiling c-ares and using the autotools build system, CARES_RANDOM_FILE will not be set, as seen when cross compiling aarch64 android. This will downgrade to using rand() as a fallback which could allow an attacker to take | ||
| CVE-2022-4904 | — | < 1.19.1-1.el9 | 1.19.1-1.el9 | Mar 6, 2023 | A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity. | ||
| CVE-2021-3672 | — | < 1.13.0-6.el8 | 1.13.0-6.el8 | Nov 23, 2021 | A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality |
